The Colerain Fire Department warned that even though lakes may look frozen solid, often that is not the case.

"The biggest thing to think of is there is no such thing as safe ice. All ice should be considered dangerous unless it is in an ice skating rink," firefighter Tom Stall said.

His crew will be training on thin ice Saturday so it will be ready in case anything bad happens.

Even though we have had days of freezing weather this week, firefighters said it was still not long enough to completely freeze some ponds and lakes.

Beckett Park in West Chester installed a shallow pond last winter but because of warm temperatures this is the first time it has been cold enough to allow skating.

"I think it is a great idea because it is very shallow. Not like the other ponds that can be kind of deep. It is made specifically for this, so it is a great idea," West Chester resident Steve Mullen said.
